Get A QuoteEach boiler is given a boiler horsepower (BHP) rating based on the steam output capacity at 212°F and 0 psig. For this calculation you will enter the steam load in pounds per hour which will be divided by a constant of 34.5. This number represents the thermal energy rate required to turn 34.5 lbs of water at 212 °F to steam in one hour.

Get A QuoteOne boiler horsepower = 34.5 lbs/hr of steam (or water) from and at 212o F. We also know that one-gallon of water weighs 8.37 lbs. To calculate the storage tank needed use the following formula: BHP X 34.5 ÷ 8.337 lbs ÷ 60 min. X 10 = minimum useable capacity in gallons. For example if you have a 500 HP boiler the calculation will be as ...
